Just a Defense Against the Dark Arts Professor

There are only theories, and of course there is no way to determine whether this magic will work as Sherlock thought it would in the end.

But he couldn't find anyone to experiment with.

He could only be sure that if the information in the Hall of Souls was correct, then it would be successful.

Sherlock didn't worry too much about whether it would work or not. He had already completed everything he could. Whether he could succeed as he expected would only depend on fate and Snape himself.

After coming out of the Hall of Souls that day, he took good care of himself, then had a full meal, left Amy in the Department of Mysteries, and went back to the Leaky Cauldron.

After Sherlock went to the Ministry of Magic, Snape stayed here.

He has no nostalgia in this world except for Lily, and he doesn't know what he can do besides trying to save Lily.

When Sherlock pushed the door open, he was throwing a mouse liver into the crucible, and raised his head and looked at Sherlock expressionlessly.

"What are you doing back?"

Sherlock stretched and slumped down on the chair as soon as he entered the door.

"What? You don't welcome me? If you don't welcome me, I can leave, but you can't even think of a way to save Lily!"

He said this, but his body showed no intention to move, and he was still lying lazily on the chair.

Over the past few days, Sherlock has lost three kilograms of weight by chewing on obscure information. Now that he is relaxed, he is too lazy to move.

After hearing Sherlock's words, Snape seemed to be under a petrification spell, and he froze in place motionless.

The boiled potion in front of him was still bubbling and bubbling, as if urging him to continue filling it, but how could Snape still have the mind to care about the pot of potion at this time, with two eyes? Staring at Sherlock.

"You...are telling the truth!"

"Don't be so excited yet. Listen to what I have to say first." Sherlock dissuaded him.

But obviously his persuasion had no effect. Snape could not calm down at this time. The usual indifference on his face disappeared without a trace, and he was extremely excited.

"You say it, and I'll listen." He took a deep breath, tried hard to suppress the uncontrollable emotions in his heart, and sat on another chair to listen to Sherlock.

"I told you before that I have some clues about Lily. That's because I found the source of the soul magic behind her that protects Harry."

Sherlock said in a deep voice.

"Lily finally used this magic on Harry. This is unquestionable history. The scar on Harry's head and the Dark Lord's death curse was rebounded and hit him, and he lost his power. These are all destined things."

"So we can start from these things that are destined to happen, and make some changes to the magic that protects Harry, so that it can have some impact on Lily herself."

Speaking of this, he said seriously.

"Let me explain one thing first. When I say saving Lily, I don't mean that she will not die."

Snape's face suddenly darkened again.

"Then what's the point!"

"It means so much!" Sherlock said solemnly, "I made an agreement with you before. If I can't find a way to go back within two years, we will work with you to find a way to let Lily survive. It’s not even two years yet. This method is at least another way of salvation. You can think of it as a way to guarantee the bottom line. Even if there is really no other way, it’s actually not bad.”

Snape was silent for a moment, then he looked up at Sherlock.

"How are you getting on with your time at the Ministry?"

Sherlock sighed and shook his head.

"There has been no progress. The research on time in the Department of Mysteries is all about the past, so there is no way to provide any help. To tell you the truth, I really don't have much hope for going back now, but I just don't want to give in. I just want to continue to find a way.”

As he spoke, he took out the results of his painstaking research these days from his pocket and handed the magic notebook to Snape.

"You have to find a way to give this to her yourself, and I can't help you. Let me remind you again Snape, no matter whether we can go back in the end, even if we really want to change history to save Lily, before we really plan everything Before it gets better, you'd better not make any changes casually, even if it's slightly different from the original, it will have a huge impact on the future. "

Snape took the note from his hand. His eyes were empty, as if he was thinking about Sherlock's words, and also as if he was thinking about how to give this note to Lily and make her feel that it was nothing. question.

The things had been delivered, and Sherlock had no reason to stay any longer. He stood up, patted Snape on the shoulder, and turned to leave.

Just when he opened the door and was about to go out, an indifferent voice suddenly came from behind him.

"Thanks."

Sherlock's body paused slightly, and he didn't respond. He just stretched out his hand and waved, and then used Disapparation to leave the Leaky Cauldron.

In Room 10, the pot of potion that had been used up long ago was still bubbling. Snape looked at the magic notebook in his hand, and the knuckles of his five fingers became a little tight due to too much force. whitish.

Those empty and cold eyes seemed to ignite a small flame called hope in the deepest part.

...

It was already 11 o'clock at night when Sherlock returned to the Department of Mysteries.

At this time, the Ministry of Magic had already fallen into silence, especially in the Department of Mysteries.

Because he was afraid of waking up Amy, who was probably already asleep, he did not choose his own office as the location for his apparation, but instead came to the black hall.

As soon as the Apparation landed, Sherlock noticed something was wrong.

Among the twelve doors on the circular wall, one black door is actually open!

He frowned subconsciously and walked lightly to the black door that was opened a crack.

After staying here for so long, Sherlock has naturally been able to distinguish what the rooms behind each black door are. The door that was opened is the room where there is usually no resident silent person to study - the Brain Hall.

Everyone in the Department of Mysteries has their own division of labor, and the Hall of Brains is an area that no one is studying at this time. Generally, no one will open this door, not to mention it is the middle of the night.

Sherlock squinted and took out his wand, and at the same time scattered a dozen wands floating around him. He gently pushed open the door of the brain hall.

The place is still so empty, with only one table, and the white brain swimming in the dark green liquid in the huge glass water tank in the center is also very conspicuous.

They are like jellyfish in the sea, with their thought tentacles floating below, looking harmless to humans and animals.

Sherlock's attention was not on these things at this time. His eyes were fixed on the doors in the brain hall.

One of those doors couldn't be opened before, but now it was ajar, with a gap clearly visible.

The door that had been sealed before was opened!

Sherlock walked very lightly and cautiously walked to the door.

The area that controls magic stretches out, peeking into the room through the opened door.

There was no one in the range that he could sense. The room seemed to be filled with rows of shelves, and on the shelves were silver light filaments stored in long cylindrical glass bottles.

Sherlock only hesitated in his mind for a few seconds before making a decision, reaching out his hand and pushing the ajar door open.

The door seemed to have not been opened for a long time, and the rusty hinges made a long squeaking sound, which was extremely harsh in the quiet space.

The room was very bright, and even if someone came in, no lights would turn on by themselves.

"Fluorescence."

Sherlock chanted the spell, and the wands floating around him lit up with bright fluorescence.

A dozen lighting spells can illuminate a very far range, and one can see clearly within a radius of fifteen meters.

This room is unusually large. Although the boundary cannot be seen, Sherlock estimates that even the Death Hall, which is half the size of a football field, is not as spacious as it.

And looking directly with the naked eye, he finally saw clearly what those silver strands of light stored in glass bottles on the shelf were.

Sherlock had seen something exactly like this before.

During the semester when the Chamber of Secrets was opened, Dumbledore took him to see his past memories, and what he extracted from his brain with a wand were these silver threads of light.

Sherlock looked around at the thousands of silver rays of light on the shelves around him, all of which were memories of all kinds!

He walked gently and slowly between the shelves. Even if he deliberately lowered his steps, the sound of the soles of his shoes touching the ground was still clear.

The wands floating around also followed his steps and went deeper into this room full of memories.

Just as he once again crossed a row of shelves and had walked more than ten meters, the sound of hurried footsteps suddenly came from outside the room.

The door of the room where various memories were stored was once again opened from the outside. Mrs. Selwyn walked in with an angry look on her face and saw Sherlock who was getting deeper and deeper.

"What are you doing here! Who let you in!"

Sherlock stopped and explained.

"The door to this room was opened before I came in..."

However, before he had finished speaking, Mrs. Selwyn changed her previous gentleness and interrupted him sharply.

"Get out! I don't care why you came in! Now, immediately, immediately! Get out!"

Sherlock had no intention of getting to the bottom of it. This matter had nothing to do with him in the first place. Since Mrs. Selwyn's reaction was so big, he had no need to stay and continue to get into trouble.

After he left the Hall of Memory, Mrs. Selwyn looked nervously around the room, which was about the size of a football field. After finding no one, she carefully touched the door on the right wall. a place.

Immediately, a wooden cabinet suddenly popped out of the smooth wall with no gaps visible. Inside, there were memories that were no different from the glass bottles on the shelf.

She carefully tapped the number of memories, and after making sure that none was missing, she let out a long sigh of relief.

After changing the secret compartment back to its original position, Mrs. Selwyn left the memory hall and locked the door again with special magic from the outside.

The memory hall fell into darkness again.

After Mrs. Selwyn left, the place was quiet for another ten minutes, and then a thin figure jumped gently from the ceiling, and the sound of falling to the ground was extremely clear in the empty room.

The location where he was hiding was at the deepest point where Sherlock walked, eleven or twelve meters further in.

If Mrs. Selwyn hadn't suddenly appeared and kicked him out, Sherlock would have been able to sense the presence of the person hiding on the ceiling if he had taken two more steps forward.

Unfortunately, this is no longer possible.

The thin figure quickly walked to the wall on the right side of the memory hall, found the spot that Mrs. Selwyn had just touched, and pressed it gently, and then the hidden compartment that contained certain special memories appeared. It popped out again.

The silver light shone on the young face of the figure. He stretched out his slightly trembling hands that seemed a little excited, took away the three bottles of memories with the label "Clark Selwyn" and put them in into his pocket.

Then, he drew out his magic and used phantom to leave the memory hall that was sealed from the outside.

And all this he did was not discovered by anyone.

the next day.

Mrs. Selwyn comes to Sherlock's office to find him.

"Sorry, I got a little excited last night, Watson."

Although she was apologizing, changing her surname instead of her first name showed her coldness.

Sherlock waved his hand.

"It's my turn to apologize to you, madam. When I saw the door to that room was opened, I should have told you as soon as possible instead of going in to investigate myself."

That's what he said on the surface, but if he really wanted to do it, then he would be really brainless.

Mrs. Selwyn frowned.

"You didn't open that door?"

Everyone could hear the distrust in her tone, and Sherlock sighed deeply in his heart.

With this suspicion, his actions in the Department of Mysteries will not be so convenient in the future. If he studies other things, he will also be labeled with ulterior motives.

"I did not do such a thing, madam. When I entered that room, I also wanted to find the person who opened the door."

Mrs. Selwyn nodded slightly and said calmly.

"That may be the case. But in the future, you should ask less about things other than time research, and just focus on your own work."

"Okay, ma'am."

Sherlock nodded and said.

At this time, he was already thinking about leaving the Ministry of Magic.

From what he knew now, these magical studies in the Department of Mysteries would not help him at all in his quest to return to the correct timeline.

And the Horcrux magic was an unexpected gain.
